April 14, 2012, 12:46 PM
When I jump pin 1 and 2 I ghet excellent flow fuel into a
small container for good 30 seconds...
then I install MAS relay (which has fuel pump relay inside)
and only get trickle for 2 seconds...tried used spare....flows good for only 3 seconds....
is it possible both MAS relays defective.......or isthere other possible electrical vudu thing going on ???

Recently changed fuel pump, plugs, wires, distributor cap and checked coil resistance: .8 ohms primary
8,300 ohms secondary cold. Seems ok.
Any suggestions where to go from here ??

sputter is random...started about 2 weeks ago i notice more obvious when go from stop to cruise speed...once cruise about 60/70 mph its better....replaced fuel pump located under chassis right side rear passenger area about 6 months ago, plugs, distributor rotor/cap...running excellent...recent sputter getting worse as time passes...TX
